To (1 7 1 whom, it 'lIh/bj/ concern:

Be it known that LLAHBERT IIERLI'rscHKA, a citizen of the German Empire, and a resident of Dusseldorf, Germany, have invented certain new and useful Improvements in Centrifugal Machines, of which the following is a specification. 7

This invention relates to a centrifugal machine so constructed that the liquid to be treated is caused to ascend through the entire apparatus, so that a thorough separation of the lighter parts is effected.

In the accompanying drawings, Figure 1 is a vertical central section of my improved centrifugal machine. Fig. 2 is a horizontal section on line A B, Fig. 1; and Fig. 3 is a side View of the liner.

The letter 6 represents a rotatable drum containing a central milk-tube a, which receives the milk at its upper end and discharges it from its perforated lower end into a chamber 12, where the heavier impurities will settle. The sloping roof of this chamber is perforated, as at c, and admits the liquid into the lowermost passage of a liner 8. This liner is composed of a strip of metal bent into the form of a continuous conoidal spiralr'. e, a spiral each winding of which is of truncated conical form. The outer edge of the liner 3 abuts directly against the inner Wall of the drum t, and thus a continuous tortuous passage is formed within it. The blue milk escapes by openings 7t" and passage 70 between the upper side of the liner and the bowl-Wall. The inner edge of the liner abuts against a tubular jacket (Z, arranged concentric to tube a, Fig. 2, and provided with a number of perforations that communicate with the inner open edge of the liner 3. Thus While the blue milk is by centrifugal action thrown outward to escape at k k' from the periphery of the liner the lighter cream Will separate at the center and will be conducted into the jacket (Z to be ejected through openings d.

What I claim is- A centrifugal machine composed of a rotatable drum, a tubular milk-shaft extending therethrough, a conical spiral liner which abut-s at its outer edge against the drum, a perforated jacket that communicates with the inner edge of the liner, and a passage for withdrawing the blue milk from the outer edge of the liner, substantially as specified.

Signed by me at Dusseldorf, Germany, this 1st day of May, 1899.
